Quit/died with about 10 characters, tried creating a memorial file and several other options then restarting (and even going to main menu an starting a new game) and nothing happened.
EDIT:
Can reproduce it only in a more specific scenario:
Die/Quit, then click ALL the death menu options one after another from top to bottom (l/s/h/i/f) and then restart. Game dies every time.
Managed to narrow it down to: if I click menu options at least four times in any configuration (like 3x view inventory 1x generate memorial file) the game will crash on restart.
Nothing out of the ordinary happens with less than 4 menu choices it seems.
